Easily create a Postgres/MySQL connection pool


Easily create a Postgres/MySQL connection pool (postgres only until I get MariaDB/MySQL working on my new Ubuntu 13.04 dev machine).

Behind the scenes it returns an any-db pool which can be used as described here.

Install the module with: npm install db-pool

Create a config/database.js containing something like

exports.app1 = {
  defaults: {
    driver: 'postgres',
    min: 5,
    max: 20
  development: {
    database: "development",
    username: "username",
    password: "pass"
  production: {
    database: "production",
    username: "username",
    password: "pass",
    port: 9999
  test: {
    database: "test",
    username: "username",
    password: "pass",
    host: "some.hostname",
    min: 15
exports.app1 = {
var db_pool = require('db-pool');
// Optionally specify an alternative config file (default is to use /config/database.js) 
// Create the default pool (from app1) using NODE_ENV=development|test|production 
var test = db_pool.pool();
// Create a pool to a development database 
var dev = db_pool.pool('development');
var app1_dev = db_pool.pool('app1.development');
// Create another pool to a different database 
var test = db_pool.pool('test');
// Show the known connections. Active ones have pool, connStr and merged default attributes. 
// Run a query 
dev.query("SELECT 1", function (err, results) {
  // Terminate all active pools 

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
